employment of the usual suspension-cords and counter-weights.

A further object is to provide a casing or housing having a plurality ofaniilrictionrollers journaled therein and adapted to yieldably engagethe window-sash for holdi ing the latter in adjusted position.

A further object is to provide means for locking the roller-supportingframe within the casing and means interposed between the casing androller-supporting frame for yield ably supporting the latter inengagement with the window-sash.

A still further object of the invention is to generally improve thisclass of devices, so as to increase their utility, durability, ndelliciency, as well as to reduce the cost of manufacture.

With these and other objects in view the invention consists in theCORSLl'llC/ilOll. and novel combination and arrangement of partshereinafter fully described, and illustrated in the accompanyingdrawings, it being understood that various changes in form, propertions, and minor details of construction may be resorted to within thescope of the appended claims.

In the accompanying drawings, forming a part of this specification,Figure l. is a perspective view of a portion of a window frame and sashprovided with a holder constructed in accordance with my invention. Fig.2 is a longitudinal sectional view of the same. Fig. 3 is a transversesectional view taken on the line 3 3 of Fig. 2.

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

The improved holder is principally dcsigned for use on windows,iransoms, and similar closures and by way of illustrz'rtion is shown inposition on a window of the ordinary construction, in which 5 designatesthe window-frame, 6 the lower sash, and 7 the upper sash.

The device consists of a substantially rectangular casing or housing 8,designed for attachment to a window frame or sash and having one sidethereof open and its end walls provided with laterally-extending lugs 9.

The casing S isseated in a mortise or recess 11, prrd'erably formed inthe \\"ind owframe 5, and yieldably supported within the casing is aroller-carrying frame 11, provided with spaced perforated lugs 12,between which are mounted for rotation on stub-shafts 13 suitablerollers 14, the peripheries of which are provided with rubber tires 15for engagement with the adj accnt window-sash.

Secured to the rear wall of the casing 8 is a supporting-plate its,having its opposite ends offset to produce laterally-extending arms 17,which bear against the adjacent ends of a flat spring 18. The centralportion of the spring 1.8 providJd with a depression 19, definingoppositrly-disposed shoulders 20, and seated in said depress-ion is aconvex porlion 21 of an auxiliary spring 22. The auxiliary spring 22 issecured to the spring 18 by means of a pin or lug 23, which extendsthrough an opening or recess 2 L in the rear wall of the casing, therebyto permit free expansion and contraction of the main and auxiliarysprings. The opposite ends of the spring 22 are deflected laterally andbear ag rest the roliar-supporting frame 11, so as to yicldably supportthe rollers 15 in engagement with the window-sash, and thus hold thelatter in adjusted position.

Secured to the lugs 9 are detachable plates 25, the inner ends of whichextend in the path of movement of the roller-supporting frame 11 andserve to prevent said frame from being forced outwardly through theopening in front of the casing, said plates being secured to the lugs 19by screws or similar ilastening devices 26, which engage thewindow-frame 5 and also serve to fasten the casing or housing inposition on said frame. it will thus be seen that the main and auxiliarysprings will exert an outward pressure on the rollersupporling frame andyieldably support the rollers in engagement with the sash, thus servingto hold the sash in adjustcd position without the employment of theusual suspension cords and weights. The rollers also prevent rattling ofthe window and in a measure dispense with the employment ofweather-strips.

IIO

While the holder is shown applied to a window-frame, it is obvious thatthe same may be mounted on the sash with the roller bearing against theWindow-frame, the result accomplished being the same in both cases.

It will of course be understood that the rollers may be made indifferent sizes and that one or more of said rollers may be used inconnection with each sash.

From the foregoing description it will be seen that there is provided anextremely simple, inexpensive, and el'licient device admirably adaptedfor the attainment of the ends in view.

Having thus described the invention, what is claimed is 1. In asash-holder, the combination with relatively stationary and movable memler of a casing secured to one or" said members and having an apertureformed therein, a roller-supporting frame slidably mounted in thecasing, rollers journaled on said frame and adapted to bear against theadjacent member, a spring bearing against the casing and provided with acentral depression, an auxiliary spring bearing against therollersupporting frame and having its convex portion adapted to engagesaid depression, and a pin uniting said springs and extending throughthe aperture in the casing.

2. In a sash-holder, the combination with relatively movable andstationary members, of a casing secured to one of said members andprovided with an aperture, a rollersupporting frame slidably mountedwithin the casing, a plate secured to the casing and having its oppositeends offset, a spring bearing against the ofi'set ds of the plate, anauxiliary spring. caring against the roller-supporting frame, and a pinconnecting said springs and slidably mounted within the aperture of thecasing.

3. In a sash-holder, the combination with relatively stationary andmovable members,

of a o secured to one of said members, a clamp .-g member arranged W1thin the casing EMIL BUJEWSKI.
